Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3. It has found numerous applications spanning from ...

University of Utah mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory, ...

Hotter objects typically glow brighter than cooler ones, making them stand out in infrared images. But a newly designed coating bucks the rule that hotter equals brighter. For certain wavelengths of ...
